Description
Technical field
The present invention relates to the method that network and equipment communicate, relate in particular to the method that a kind of hot backup redundancy computer communicates by redundant network and miscellaneous equipment.
Background technology
In the Distributed Computer System of high reliability, often there is computer redundant more than two or two to carry out identical work, when a computer glitch, just substitute with another computer.Redundant computer group has two kinds of working methods usually: cold standby and heat are equipped with.In the cold standby working method, whenever having only wherein, a computer is called main frame in work; Other computer then shuts down or dormancy, is called standby host; When main frame breaks down, then start or wake an available standby host up and substitute its work, at this moment, this standby host renames as main frame, and main frame originally then renames as standby host.Be equipped with in the working method in heat, whenever have two computers at least in concurrent working, but have only wherein computer output result, this has the computer of output to be called main frame; Other computer is called standby host; When main frame broke down, then another standby host that is moving substituted its output, and at this moment, this standby host renames as main frame, and original main frame renames as standby host owing to having cut off output.With respect to the cold standby working method, still less thereby have higher reliability active/standby machine switching time that heat is equipped with working method.
In the Distributed Computer System of high reliability, every computer often transmits identical data with two or more redundant IP network respectively, when a network failure, just substitutes with another network.Redundant network also has two kinds of working methods usually: cold standby and heat are equipped with, and in the cold standby working method, only send data by one of them network usually, are called major network; Other network does not send data, is called net fully; When major network breaks down, then send data by an available net that is equipped with, at this moment, this net that is equipped with that sends data renames as major network, and major network originally then renames as net fully.Be equipped with in the working method in heat, every bag data of transmit leg will send in all redundant networks, and the recipient will receive a plurality of (respectively from heterogeneous networks) identical packet like this, the recipient often only handles the packet that arrives at first, and abandons other packet.With respect to the cold standby working method, still less thereby have higher reliability the fault time that heat is equipped with working method.
It seems from the above, respectively at redundant computer group and all ripe at the monotechnics of redundant network.But, how many redundant computer groups of Hot Spare are each other done that as a whole (this external equipment may be single computer by redundant network and external equipment, the also another set of redundant computer group that may be made of many computers) communicate, present method has two kinds:
A kind of method is to increase a prepositive communication computer, and this prepositive communication computer substitutes redundant computer group and external equipment communicates by redundant network.Specific implementation is: all communicate by redundant network respectively between prepositive communication computer and main frame, standby host, the external equipment.Which platform computer prepositive communication computer can determine or discern is main frame, and the data forwarding that it sends main frame is given external equipment, and gives main frame and standby host the data forwarding that external equipment is sent, thus to outside device mask current any platform computer be main frame.External equipment not with the redundant computer group direct communication, only communicate with fixing prepositive communication computer, do not need to consider therefore that active/standby machine switches, simplified processing.But in this method, prepositive communication computer in case break down, will cause system unavailable as single nonredundancy computer cluster, and therefore, the reliability of system will reduce.
Another kind method be all Hot Spares redundant computer group all directly and external equipment communicate by redundant network.Specific implementation is: in the redundant computer group, have only main frame to send data to external equipment by redundant network, standby host is not to outside equipment sending data; When external equipment will send data to the redundant computer group time, then data had both been sent to the main frame of redundant computer group, also issue the standby host of redundant computer group.In this method, on the one hand the sendaisle number of external equipment has increased, and on the other hand, active and standby machine is difficult to realize the transparency to external equipment, and therefore, the availability of system will reduce.
Above method does not all reach " computer and network being realized dual fully redundance with transparent way " problem.In using the Distributed Computer System of redundant network, often require the redundant computer group subsystem formed by two and above computer still to be communicated as single computer and other computer or subsystem.

Embodiment
The present invention will be further described below in conjunction with specific embodiment.
Embodiment
Below, communicate by miscellaneous equipment outside the redundant network formed by two networks and the redundant computer group with the hot backup redundancy computer cluster formed by two computers and to be example, introduce the specific embodiment of the present invention:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, suppose that redundant network is made up of two networks: X net and Y net, redundant computer group C1 is made up of two computers: C11 and C12, miscellaneous equipment is called C2 outside the redundant computer group, C2 may be a computer, also the redundant computer group that may be made up of many computers.
Step 1, redundant computer group dispose a fixing open IP address respectively at each network in the redundant network:
(1-1) for redundant computer group, the respectively corresponding fixing open IP address of each network in the redundant network.For example shown in Fig. 2, Fig. 3, Fig. 4, R1, B1 are that redundant computer group is respectively in X net, the online corresponding open IP address of Y.
(1-2) every computer all is connected on each network in the redundant network by network interface card in the redundant computer group, and every computer is connected to the implicit IP address of the respectively corresponding acquiescence of each network interface card on the redundant network.For example Fig. 1 is represented, computer C11 has that two network interface cards are connected respectively to the X net, Y is online in the redundant computer group, corresponding acquiescence implicit IP address is respectively R11, B11, computer C12 has also that two network interface cards are connected respectively to the X net, Y is online, and the implicit IP address of corresponding acquiescence is respectively R12, B12.
(1-3) for each network in the redundant network, the network interface card that can only have a computer to be connected to this network in redundant computer group is configured to open IP address, and the network interface card that other computer is connected to this network then is configured to the implicit IP address given tacit consent to.For example among Fig. 2, Fig. 3, Fig. 4, in the redundant computer group when computer C11 when the online network interface card of X is configured to the online open IP address R1 of X, then computer C12 is configured to the implicit IP address R12 of this network interface card acquiescence at the online network interface card of X; When computer C12 when the online network interface card of Y is configured to the online open IP address B1 of Y, then computer C11 is configured to the implicit IP address B11 of this network interface card acquiescence at the online network interface card of Y.
(1-4) each network interface card of every computer generally all is configured to the implicit IP address given tacit consent to separately in the redundant computer group when initial.For example among Fig. 1, when initial, four network interface cards are configured to implicit IP address R11, the B11, R12, the B12 that give tacit consent to separately respectively in the redundant computer group.
(1-5) when detecting certain open IP address can not efficient communication the time, then select a computer from redundant computer group, the NIC address that it is connected on this network is revised as the disclosure IP address by the implicit IP address of acquiescence; Originally that network interface card that disposed the disclosure IP address then reverts to the implicit IP address of acquiescence.For example among Fig. 1, the online open IP address R1 of X is not set up, therefore can not efficient communication, and therefore select computer C11 at the online network interface card of X, open IP address R1 is revised as by implicit IP address R11 in its IP address; The online open IP address B1 of Y is not set up, therefore can not efficient communication, because the open IP address R1 of X net has been configured on the computer C11, therefore according to the principle of equilibrium, select another computer C12 rather than same computer C11 at the online network interface card of Y, open IP address B1 is revised as by implicit IP address B11 in its IP address.
Step 2, when redundant computer group will send data to miscellaneous equipment, then fixing open IP address as sending the address:
When (2-1) certain network sends data to miscellaneous equipment in certain computer in the redundant computer group will be by redundant network, if this computer be connected to this network network interface card configuration be the open IP address of this network, then with the disclosure IP address as source address, directly send to miscellaneous equipment; Otherwise these data are delivered to that computer that the network interface card on this network in the redundant computer group is configured to open IP address by network or alternate manner, are transmitted to miscellaneous equipment by that computer.For example shown in Figure 3, computer C11 passes through directly miscellaneous equipment C2 transmission data outside redundant computer group of open IP address R1 on the net at X; And online at Y, then data earlier the implicit IP address B11 by the online acquiescence of Y send in the redundant computer group on other computer C12, be forwarded to miscellaneous equipment C2 outside the redundant computer group by computer C12 by the online open IP address B1 of Y again.
(2-2) when the network interface card on certain network in the redundant computer group is configured to the open IP address of this network, if receive the data that other computer in the redundant computer group will be issued other equipment by this network by network or alternate manner, then these data, as source address, be transmitted to miscellaneous equipment with the open IP address of this network.For example shown in Figure 3, computer C12 receives the data that other computer C11 sends the redundant computer group on the net from Y, then these data, as source address, is transmitted to miscellaneous equipment C2 outside the redundant computer group with the online open IP address of Y.
Step 3, to send data to the redundant computer group time when miscellaneous equipment, then fixing open IP address as receiver address:
(3-1) when the miscellaneous equipment outside the redundant computer group will be given these redundant computer pocket transmission data by certain network of redundant network, then only the open IP address of this redundant computer group on this network sent data (giving this redundant computer group) as destination address, and can not send the data to the implicit IP address of the acquiescence of redundant computer group.For example among Fig. 4, miscellaneous equipment C2 sends data to the open IP of redundant computer group address R1, B1 outside the redundant computer group, and data can not issued implicit IP address R11, B11, R12, the B12 of redundant computer group acquiescence.
(3-2) when the network interface card on certain network in the redundant computer group is configured to the open IP address of this network, if receive the data that miscellaneous equipment is sent outside the redundant computer group by the disclosure IP address, on the one hand these data are submitted to this machine inside and handle, by network or alternate manner this data passes is handled to other computer in the redundant computer group on the other hand.For example among Fig. 4, computer C11 submits to these data this machine C11 inside on the one hand and goes to handle after the open IP address R1 of X net receives data in the redundant computer group, gives other computer C12 in the redundant computer group with this data forwarding on the other hand; The computer C12 of redundant computer group submits to these data this machine C12 inside on the one hand and goes to handle after the open IP address B1 of Y net receives data, gives other computer C11 in the redundant computer group with this data forwarding on the other hand.
(3-3) when implicit IP address that the network interface card on certain network in the redundant computer group is configured to give tacit consent to, if receive the data of miscellaneous equipment outside the redundant computer group that computer of being configured to open IP address on this network transmits, then these data submitted to this machine inside and handle.For example among Fig. 4, in the redundant computer group computer C12 X receive on the net that computer C11 transmitted from redundant computer group outside after the data of miscellaneous equipment C2, these data are submitted to this machine C12 inside go to handle; In the redundant computer group computer C11 Y receive on the net that computer C12 transmitted from redundant computer group outside after the data of miscellaneous equipment C2, these data are submitted to this machine C11 inside go to handle.
